Clinical comparison of platelet-rich plasma injection and daily celecoxib administration in the treatment of early knee osteoarthritis: A randomized clinical trial.
Trial report in Journal of applied biomedicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOral and topical nonsteroidal anti-inflammatory drugs (NSAIDs), analgesics and intra-articular corticosteroid injections are the recommended first line of treatment for knee osteoarthritis (OA); however, they have serious side effects. Platelet-rich plasma (PRP) has been posited as an effective and safer alternative treatment for knee OA. Hitherto, there is only one study comparing the effectiveness of PRP against an NSAID. AIM OF THE STUDY: The aim of this study was to determine the effectiveness of PRP against celecoxib in the treatment of early knee OA.
methods60 patients with knee OA grade II and III were randomly alocated in two groups. Group 1 received one injection of autologous PRP in each affected knee, with a reinjection after 15 days; Group 2 received 200 mg of oral celecoxib each 24 h for a year. Visual Analogue Scale (VAS), total Western Ontario and McMaster Universities Arthritis Index (WOMAC) and WOMAC subscales for pain, stiffness and function were measured at baseline and at 1, 3, 6 and 12 months after the start of the treatment.
resultsAt the end of the study PRP was significantly better than celecoxib (p < 0.05) in improving VAS (40.40%), total WOMAC (58.95%) and WOMAC subscales of pain (50.60%), stiffness (34.13%) and function (51.90%). Significant differences remained after adjusting for age, sex or knee OA grade II or III.
conclusionsIntra-articular PRP is significantly better than celecoxib in improving pain, function and stiffness in early knee OA. This significant difference is independent of age, sex or knee OA grade II or III.
